Oxytocin (10 mg Vial)

Oxytocin is a peptide hormone (nonapeptide) known for its role in childbirth and lactation, and it also influences social bonding and behavior. In research settings, synthetic oxytocin is used to explore effects ranging from stress and anxiety to social cognition. Oxytocin 10 mg is available as a lyophilized powder for research use, requiring reconstitution before dosing. This protocol compiles evidence‑based guidance on dosing, administration, and storage for oxytocin peptide.

Dose
10–40 IU per administration
Frequency
Once daily or as needed
Timing
Morning or 30 minutes before social/therapeutic context
Duration
4–8 weeks (research protocol dependent)

Neuropeptide hormone. Most commonly administered intranasally (20-40 IU per nostril) or subcutaneously (10-20 IU). Research areas include social bonding, anxiety reduction, and gut motility. Effects onset within 15-30 minutes. Do not exceed recommended doses — paradoxical effects may occur at high doses. Store reconstituted solution refrigerated and use within 30 days.
